Wasn't aware of any controversy. When mtn.biking was just getting started, I cut my teeth on a fully rigid bike. Then went to a hardtail (still have it). If I was riding more, and was younger (don't figure I'd be riding off-road a lot longer-never expected to still be off-road at 71 tho, so who knows?), I'd be riding a full suspension. Unless a rider finds the maintenance and upkeep on extra suspension point, shock, and fork to be intimidating, I don't see any reason not to take advantage of full susp. on rougher trails. There have been times when I wish I had one, but can't justify the expense for the amount of off-road riding I do these days.
