I reviwed info about the several types and listed the properties to
consider:
passive noise canceling
active noise canceling
reliability and durability
style
comfort
whether manufacturer will repair and stand behind the product
cost
I then decided which was the most important to me. Because I have a slight
hearing loss, I decided that passive and active noise canceling should be
the most important. I chose Lightspeed.

Joe,
Perhaps you've a stock bearing number that you could share with us?
It's be worth the
$40 to me too.

I have been trying for a while to figure out a way to get the hobbs running
automatically at "engine start" without having to install an oil pressure
switch with the pressure sensor. I would have to install a Tee but the brackets
for the radiator are in the way. I just happend to be browsing the entries on
the aeroelectric list and found this post from Gerry Holland. I am going to
use this, I thought for some here it might be useful:

Bob Hi!
I'm using a device called Power Genie to supply start and stop Voltage to
Hobbs Meter. About to start my Rotax Engine. OK?

There's an even cheaper and easier way. Here's the link
http://www.800-airwolf.com/pdffiles/ARTICLES/part33.pdf
Go to page 3, at the top of the page where it discusses "Full Wave Bridge
Rectifier". I've used this method with my 503 Rotax with a Hobbs for several
years and it is foolproof, reliable, and accurate. Around $2 from Radio
Shack. As I recall, the part number 276-1171 has been superseded but the new
part number is standard stock.

Hi Brian,
I went thru the same process of thought when I wired my Jabiru motor and
Hobbs. In the end I just decided to attach the Hobbs positive lead to
the ALT switch. I only activate it when the motor is running and always
shut it off before turning the Master switch off. Works fine for me and
eliminated oil pressure and other complicated parts.

Yes, I agree this is a reasonable method. For example on Rotax 912 engines,
using this technique (see
http://ch701.com/Builders%20Resources/electrical/912engine/jon_wiring.htm)
even if you accidently leave the alternator switch on, the red alternator
lamp will light up when the engine is shutdown. No special parts needed!

I got them at:
US Bearings & Drives
Seattle, WA 206-762-3800
2 - Timkin 03062 Tapered Roller Bearing Cone
2 - Timkin 03162 Tapered Roller Bearing Cup
They had a parts book that enabled us to select a cup that
would fit the wheel and a cone that fit the 5/8" axle.
Verify that your inner and outer diameters match these parts.
I have the Matco wheel that takes a 5"x5" tire.
Matco told me that they use tapered bearings with a 3/4 inch
axle, and the same wheel for some applications. So the wheel
was set up for tapered bearings. The wheel needs a ridge on the
inner side of the bearing cup to hold the cup in place.
The front axle already had spacers that hold the cones in place.
I did have to use shorter spacers. I cut a variety of sizes at
home so that I didn't have to struggle on the tarmac.
I like the design of the tapered bearings.
Even if they fail the wheel can remain aligned with the axle.
(I've seen failed tapered bearings, on heavy equipment, in the
field, that we found during preventive maintenance. Didn't
know until we looked.)
When my ball bearings failed, as I was turning for a runup,
the front wheel flopped over. If that had happened during a
landing I may have cartwheeled. I feel lucky.
