You can get some really solid rigid forks that are tough enough that the wheel will blow up before the forks let go. But if you're jumping the bike then you'll want good forks. Frankly if you're jumping lots and high then you need to expand your budget and get something with a solid rep for laughing off lots of punishment. There's nothing at all wrong with the 100 mm travel forks but I consider the Avalanche to be more of a cross country style bike that is more happy sticking to drops of less than 3 feet for riding on a regular basis. If you are thinking of going bigger than that I suspect you've got the wrong sort of bike right from the get go and should have gotten a more burly urban or mountain big drop bike.
