Smaller mountains are still mountains and require knowledge of mountain
flying. The only thing the Welsh mountains don't have that the Rockies
do is the very high density altitudes.

Well, the difference between the short mountains and the rockies also is that
you can get above most of the mountain effects by getting several thousand
feet above them. This you can do if the peaks are 3500, but harder when they
are about 9000.
