Better quality sets sported filament windings on the main transformer. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | It's what you learn, after you know it all, that counts.

Skikes are like roller skis but they have larger pneumatic tyres, brakes on both, and they work with normal shoes. That makes it easier to keep your skin attached. Clifford Heath.

Falling onto dirt and rocks and >pavement might not be as fun.I have an 11-year-old grandson who is, for all intents and purposes, _pro_ level at ice _and_ roller-blade hockey (*) He takes some might nasty falls (he is, as you might expect, somewhat combative ;-), but he's padded every which way from Sunday. (*) He is the go-to-guy for the _whole_ league when a substitute player is needed. He's the first "jock" that I know of in the family history. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | STV, Queen Creek, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | It's what you learn, after you know it all, that counts.
