Using the 3x easy, 3x medium, 3x hard principle is a good guide with the 3 easy being doable by a rider from a lower grade and the 3x hard set around the level of the 3x easy of the next grade.
Here in WA Trials is booming with 80-90 riders being common place with 15 riding Black (beginning to end no markers), 25 Trial 5, 20 T4, 6 T3, 5 T2, 3 T1. So as everybody has pointed out it is a pretty bottom heavy field below T 3.
When I set for T 3 I believe they should be able to do at least basic hops, basic nose wheelies and be able to carry the front wheel off a log they can't roll off. For our T4 riders I believe there are possibly 3 or 4 riders that have or should reach my T 3 criteria in the next season or two.
So what's the answer for WA if we want to produce another Kyle or Neil in the next 5 years? I would say we carry on the same way we are already are in setting WA Trials. Our Black plate over the last 3 Years has gone from 2 to over 15 which is awesome and I would say our T5 severity has only increased slightly which is surprising.
Does WA need a T4+ C+? I would say no, a rider in C should be pretty capable of static balancing, 60cm + logs and the occasional hop our T4 scores vary from 20 for the seasoned Vet to 100 for the crash and bash brigade who are the ones who will put in the off Trial Practice in.
I remember the nice segmented graph put out by MA on the introduction of T1 _ T5 explaining the nice incremental steps that need to be taken for consistency......A week later certain Eastern States had already stuck a T4+ into the mix.
