I've also \"investigated\" the trad climbing at De Pakhuys, recently, and many years ago, before bouldering and sport climbing, and agree with you Snort. Some excellent lines there and, yes, many of those bolts are unnecessary. Having been there years ago I was somewhat dismayed by what I found there recently. The bouldering impact up there, and the bolts, left a sour taste! I know we have to be all PC and allow sport climbing its place, BUT it's now getting ridiculous.
Re. the main Pakhuis Crags, I've done a few of the classics and many of them are worthwhile. ADK's so called \"book of lies\" describes most of them. Quite accurately actually.
Excuse what might be misconceived as an attack on sport climbing but I have just had a cervical fusion and can't climb for months, and am quite bitter about that! There is definitely a little niche somewhere for sport climbing.
