If you are a heavy person, expect a lot of spoke breakage from either kit, (although it is not uncommon for lighter personnel to have the same problem). It is often necessary to order a rear wheel with at least 12 guage spokes, (which can't be replaced if they break), or get a good rim, and hub, and have the wheel custom built with 10 guage spokes by "The Wheelmaster" in Auburn, WA, (if one breaks the wheel is guaranteed for life, and the broken spoke will be replaced). I did the latter of the two, and haven't regretted it even slightly, because I haven't had any problem with spokes since. Also you might read about using epoxy cement to keep your drive ring centered, (GEBE), or wrapping wire with solder, or plastic tie wraps where your spokes cross to make the wheel stronger. In my opinion if such drastic measures are necessary to keep the integrity of the wheel/drivering, then much thicker spokes are needed. Needless to say, I don't need to use "field expediency" measures to hold my rear end together...lmao. Love those big 'ol 10 guage spokes!! he he.
