The factory kit on my Tiger Cub works the best out of anything I've tried, however, I made on for the big mower a few years ago out of an old rubber bedmat. It worked great, except that my bracketry left something to be desired. Laid down some nice stripes until it fell off. But it didn't cost me anything. I'm working on a new one now. I'll use old steel rollers I picked up from a local golf course. I'll just have to buy bearings and some metal to make brackets. Just for the record, my old wb laid down some really nice stripes with no kit at all.
