dear rudy
please try and stay on topic
the argument of this thread is if it is ever ok to retrobolt existing trad routes, bolt on artificial holds or chip holds on existing or new routes
your plea for coexistence of these practices with traditional climbing and chip-free, fake-hold-free, not-bolting-cracks "traditional" sport climbing is therefore spurious. these practices are unsupportable and cannot coexist with real climbing and should be abolished, expunged, destroyed, abominated, abhorred, jihaded against, and declared anathaema wherever they are found to have sprung up like a nasty rash.
it's really simple - if you want to bolt up a sport route, find - 1) a line that will go without subversive alterations and 2) a line with no natural pro. bolt the fuck out of it, grease your skinny legs with vaseline, force your lycra on, stick clip the draws and have at'er. THAT is the only acceptable coexistence.
If on the other hand, your line has blank sections YOU can't free, or is too loose to be safe, hmmmm - maybe you should go somewhere else. Cause it sounds like your proposed line sux and there is no rock shortage in the pnw....
