I can second Denis's recommendation of heading to Canaan for tele gear. Round these parts, if you want tele gear, it's either special order thru a shop, mail order or a 3-4 hour drive to WV where you can fondle gear at Whitegrass. Neither Whitetail or Roundtop rents tele gear, but if you're bringing your boots, there might be a way, way outside shot to hook up and borrow some gear for the day. Myself and the crew I run with all use 180ish sized sticks.
If you must tele, might be prudent now to start planning a daytrip to WV, you can do it without an overnight stay, but expect to be spent on the return trip. If you can't swing a run to the Valley, the local options can be weather dependent. I really like skiing Whitetail, decent vert for these parts, ~900ft vs 600ish for Roundtop. WT's blacks are much longer and a more evenly sustained pitch than you'll find at Roundtop. But, Roundtop's double blacks are more challenging, they're shortish headwall type runs that get the juices flowing before relaxing into single black terrain. WT has much longer blue runs if cruising and carving is your thing. Depending on when you can get to the hill, crowding might be something to consider, expect larger crowds at WT than at RT if there on a wknd.
Annnnnd, watch the weather, if you're here during the predicted thaw-freeze of the next two weeks, WT conditions can be variable due to its exposure. I think RT holds onto nicer conditions when the temps start bouncing up and down. If it's a weekday morn, WT for sure, late in the day or night, seriously consider RT. Wknds can be a toss up.
When are you visiting?
I've heard thru the grapevine that there's gonna be a tele gettogether at WT, middle of Feb. No idea of the agenda (clinics, demos, etc), who knows, there just might be more than a dozen pinheads on the mountain at one time.
