Linda, I'd definately go with the steel 85's.  They are not overly negative at all and are quite manageable out of the water as well.  The 85's are -6 lbs. full and neutral when empty.  Diving dry, steels are the way to go.  Aluminum 63's might work for a light deco dive but if you are talking trimix and the Kamloops even with an excellent SAC rate, you are going to want much bigger tanks so you have sufficient air for emergencies as well.  Keep in mind, most divers diving the Kamloops are diving twin 108's or 95's.  Aluminum 80's would do but the steel 85's would be a better choice, don't cost too much more than aluminums (approx. $199 per tank new) and don't have the positive buoyancy swing of the aluminums.  If you want sometime I'll let you try a set of my 85's out to see how you like them.
