Hand guards on rec poles eh? Hmm maybe for tree / bushwhacking?
As for SL poles - esp for training - just use whatever poles you have around and buy the full hand guards. Spray paint em black or cover with stickers. Easy to identify on hill. Tips on handguards - put a wrap of black duct tape around the pole that will be beneath the guard - less slipping/rotating. Also - if you find the guard rotating, drill a small hole through bottom of the guard guard and insert a small screw. Cover with tape. When installing - slip guard on near TIP and slide UP. Add a layer or 2 of tape extending about 6 insches beneath guard. This will cushion impact a bit and reinforce pole.
Use a sharp knife or trainer scissors to trim basket to be more racy and less likely to catch on gates.
Poles come and go but handguards will last a long time.
Speaking of tape - take about 3' of duct tape and wrap carefully around your pole somewhere. In an emergency, you have 3' of duct tape with you on the hill. While I am thinking of it - add a few elastic hair bands around the pole (around bottom and slide up). Somebody at the hill always needs a hair elastic. Also useful for keeping open bags of skittles from spilling.
CHEAP Training shorts can be made by using a pair of fleece sweats and cutting off legs. They are stretchy enough to fit over boots for on and off. You can use the cut off legs for neck gaiters. The shorts are also nice for bitter cold days to wear under regular pants to keep the tush and thighs a bit warmer.
I would not spend big $$ on SL poles.
