It's kinda' like boating. You buy a 21 footer, you soon want to go bigger, like a 25' or 27', then 32' and then 45', with the latter 2 being motor yachts. Save yourself the time and money and go with a 4/6 using spindles, lowering springs, flip kit, c-notch and either a shackle/hanger or lowering block. If you get rich and the itch, then go to bags.
