In reply to Offwidth:
"many issues remain around HVS and E1: the sports range is too low from safe to bold, the conversion for safe IMHO is still too low (safe trad is harder). "
Safe trad is generally harder at any given grade than bold trad and yes we both agree it will normally feel harder than the sport top rope grade of the route to lead. However I disagree the sport top rope grades of trad routes are radically wrong in the bold table (rockfax accept this is badly named and should be the standard table of converting technical difficulty from trad to sport grades, its the one they print in their guide books). Generally the trad climbs which don't fall in to this bracket will either feature climbing that most people aren't well versed in now a days or are plain sandbags or are extremely objectively dangerous routes. I've already posted a few examples of retro bolted trad routes that fall in to these brackets, perhaps you can find some that don't? I'm not sure I still have my old Swanage & Portland guide but if I do I can dig out plenty more examples I'm sure that agree with the bold table.
" At all grades the two tables have safe route conversions at different levels"
Yes I pointed this out and rockfax accepted there were issues with the safe table, it was designed again representing technical difficulty only, but only showing safe trad routes, so that sports climbers could assess how hard trad climbs of a certain grade are likely to be. I personally think this table is flawed and best ignored, the bold table is the main table rockfax use.
" the bold table shouldn't have a 'safe' end"
Actually it should, the table just needs renaming
Personally I think the bold table is pretty good at defining the technical top rope difficulty of trad routes compared to sport grades. I can't comment on the other grade types as I haven't used them enough. The rockfax bold table seems pretty inline with the bmc and mcofs table (if you compare against safe routes in the bold table) so I reckon they are all comparing the same thing. The technical difficulty of the climbing in isolation (ie as if it was top roped).
