In reply to humptydumpty:
If you're buying local guidebooks in Catalunya (I include Lleida Climbs and Tarragona Climbs in this category, though I know some may disagree) then I don't think you need to worry about direct bolt-fund donations, unless you want to target a particular zone and/or group of equippers.
For the record: since 2010 Lleida/Tarragona Climbs guidebook sales have enabled us to purchase and pass on to equippers somewhere in the region of €10,000 worth of bolts, hangers and lower offs (and this is with bulk purchase discounts) though I need to add that this figure includes bolting gear that I've used myself in developing new routes and sectors in the region.
We have also given many climbing refugis (which are generally the epicentres of climbing deveopment in Catalunya) deals which allow them to sell our guidebooks with no money upfront and then keep between €8 and €10 per copy sold. In certain cases the revenues for individual refugis have run into thousands of euros... with obvious benefits for bolt funding.
Pete.
