Well you have to take into account points values if you are comparing the relative effectiveness of different troops.Taking into account points values maybe, but I dont see how the shorter range is no handicap. Shooting at 2 inches means they can get caught by cavalry, whereas LH Bw shoot at 4 and can never be caught by them if the do so.
And I didn't say the shorter range was no handicap. It clearly is significant when in front of enemy cavalry, but in most other situations it dosn't make that much difference. And in most situations I think 6 JLS LH will be better than 4 Bow Sw LH.
