I wish they would come back!
If you fly from a rough grass patch,as I do, the currently-fashionable carbon legs/fus mounting,is a total PIA---if the leg doesn't eventually delaminate from vertical shocks,its lack of fore-and-aft flexibility will eventually damage the mounting plate, and if you introduce soft-mounting into the bolts (eg Rawlbolts or similar),sooner or later they'll pull out and the belly pan suffers----at least with retracts all that happened was the repeated leg straightening.....
It's a pity we're such appearance/fashion slaves----a torsion-wire U/C saves a lot of grief!
