Which one would you keep? Recommendation of large 2-stroke (120 ~ 145)

[Ihncheol Park]

Hi, All,
I am trying to get rid of some of the engines, and get a new larger one.

I got

1. Hanno with Shadel Piston and Liner ( was told it was not broken in yet
and I had to add another head shim to make it turn a little easier).

2. YS 61RELS Very good compression. Clean, got it used, but haven't had a
chance to run it.  Just got header a few days ago.

3. OS 61VF only ran twice (I guess this one gotta go).  I've had all three
size of VF engines. no pump

4. Webra 61 rear exhaust with dynamix carb. no pump.

Which one would you keep?
Pipe for the engine is Hatori 650.  I have Hatori headers for the first
three engines.

My only experience in Webra was Speed 40 with TN carb.
YS and OS are pretty familiar.  I heard dynamix works really good.
Power ratings, longevity, parts availability may be the facts to choose.

I am only going to keep one and get rid of all the rest to get a larger 120
~ 145 2-stroke engine.
So far,

OS 140RX: bearing life problems, mid-range, easily available parts anywhere
in the world.

Webra/Bully 145: never heard any problem, but getting parts in Korea maybe
too hard.

Any other recommendation?
I prefer 2-stroke because of the weight problem, so unless YS come up with a
brand new 140 or larger 2-stroke, it is out.  It doesn't mean that I don't
want to use 4-stroke YS.  I still have 2 of my YS 91s and YS 63 that has
planes that fits.

Thank you,
