Block Posting

[pdiggitydogg]

So Ive read all threads on h-t and visited homemadeturbo and sonny's crx page for info on block posting.
Seems like a good cheap alternative to resleeving.

My question is does anyone actually KNOW someone who's done it, and have you actually seen it?
How well does it actually work in the long run?
Does cause stress points that cause sleeves to crack at the post point at high enough pressures?

Any other info would be appreciated
