Not sure why you accused Calsun of "shilling," but you seem to be in a mood so I'll leave you to it.
It's not a
bad mood per se

, we just seem to be straying further into things that are so marginal that they could become distractions from the goal. People can climb just fine with long chainstays and tubes in their tires; that's not what's holding the OP back.
But there is always the chance that throwing money at the problem could make the experience a little better, and inspire him to ride more, so I will end my protests here.
