The Hallucinagenic, along with the new Tranquilitas crags are now both properties of the MCSA, so the bolting that goes on there is done primarily by MCSA members. The MCSA as you well know has a bolting fund that, which helps bolters that are apart of the bolting commitee put up new routes. It also means that the bolts/hangers that are used are also standardised, which is a good thing, since you know that the bolt you're clipping is good. The MCSA does NOT however pay for the chain at the anchors for some unknown reason and therefore the people putting up new routes tend to use the cheapest stuff they can find (this is a gross generalisation, but holds true for the majority of the anchors). That's why the links are sometimes too small to accept a draw easily. It really seems odd that the MCSA standardises the entire route except the most crucial bit, the anchors. There is a set of anchors on a route on the new Tranquilitas crag where the link that has been used is not even fully welded closed!!! The MCSA must however be commended since they do put a lot of money into bolts, that in turn, turn into new routes that you get to climb. I feel that they should however have a look at standardising the chain at the anchors! Check out:
