The beauty with the DIY route to me means Custom built, Custom to the users needs. Whether that be size, shape, speed, ability or what ever and so like John S says one design doesn't fit everybody. . . Never can, never will.
Marks also correct it would turn into one big brawl.!! Bans would be getting dished out left right and centre, probably starting with me first.. Lol

Some things are just the way they are and meant to be and it takes a certain amount of effort to gain the reward. If we can help guide new folks away from the rocks then that's all I think is needed.?
