It's typically not an apples to apples comparison.
Old school loft, shorter playing length, heavier shaft, and flatter lie
Jacked loft, longer playing length, lighter shaft, and more upright lie
Two different clubs IMO-
An old school 7i at 35 loft is not the same club as a new school 8i at 35 loft, unless all else is equal, which IMO is not. Not to mention the weight difference between the heads. Again not the same club!
You still need to get fit no matter the loft!
