Best waxing

Well personally I think it's best to just wax often and for the conditions. If you need something to last forever though, use a really cold weather wax like a Swix green. I hate working with it because it's so hard to keep flowing, and it's a bitch to scrape. When dry though it is hard as steel. But if your not skiing in cold weather conditions then it's really pointless IMO.

Hot wax duh.

Swix is probably the best, but too pricey for me. I usually go with the red Briko, best balance of cost to quality for my purposes! Just experiment, you'll figure out what wax works best when.

Hot waxing will last much longer than rubbing it on with a stick. It actually gets in the base then. I guess I might try and buy some of the swix all purpose training wax. It's supposed to be for all conditions and is pretty cheap.

There's no easy way to get fast skis. Wax cycling is time consuming, expensive, and fucking awesome. if you're cheap, the most effective way to wax is to cork/razeway your skis.

Swix f4. I get a big block that lasts a year for $29. So worth it...

3x ironed in purple purl wax. zardoz liquid teflon on top of that. good luck with the lift lines.

Nothing like a hot rip off bikini wax

Hot waxing is by far the most effective method. 

Better still it to put your skis close to a woodstove or pelletstove for a few hours before scraping the wax off.  This has the same effect as using a "hotbox" so that more wax is absorbed into the base.  Aim for 120°F and try not to exceed 130°F.  The wax may turn enter a semi-liquid state, but this is okay.  Hotboxing makes the bases even harder and faster than hot waxing alone.  Also you won't need to wax quite as often.  The difference is certainly noticeable.

I also use the "warm" stuff here: http://www.tognar.com/swix-universal-wax-900g/ (red color)
Unless your looking to be 1 second faster (if that) on a 30 second race course, universal wax is plenty adequate, and cheaper than temperature-specific wax.  I would recommend the cold variety for the east coast if your planning on getting one variety.  Its harder than the "warm" stuff and will last longer. 

900g = Five 180g bars (standard size)
A single bar might last you 12 waxes?  I guestimating. 
Wax every other day if you have a sintered base (ideally), and everyday if you have an extruded base (ideally). 

Waxing makes you faster.  More importantly it makes skiing easier and protects the bases of your skis.
