I have the Gar-Aero tailwheel (with 8.50x10s on 180 gear) on my 170B, which gives me the benefit of added flotation on the tail end but I have to keep my TW tire pressure up and lose some of the cushioning you might get with a BBW. I have flown my 170B with a Scott 3200 and don't notice any...
It looks like Flight Resource has signed on as a site sponsor. If so, I'd like to thank John and company for stepping up. I've been quite happy with their customer support, and with my MT on my 170.
I have a baby bushwheel for my 170. It's great for off airport soft/rough surfaces. It only adds 3.5 lbs I believe over the Scott 3200. I also have the L-19 mainspring and it's the way to go if you need to replace yours.
