On your Turbo, HZZ, did you have the regular tracks or the ones that are bigger, that you only see on some Turbos, I think "H" models or something like that. Aqua products charges more for the bigger track ones, but some seller was telling me the regular tracks (which is what I have on regular Aquabot) stay on better. Anybody have an opinion on that. I'm semi-tempted just pick up a refurbished Turbo since you can get them for about $500 on ebay.
