This is where you'll find guys still wearing gear that was produced 10-20-30 years ago and not care for change. Then you have the now generation who absolutely think that the newest lines are the better ones and is the answer to better goaltending.
If you're a goalie that has never rocked old gear, it makes it hard for you to understand. The difference in wearing pillows versus boards is pretty obvious, but at the same time, the way you will play with this gear is as different.
Sometimes change is good and welcomed, others times not so much. The problem I can see is that you can't expect the gear to play both ways 100%. You can take modern gear and use it for pro-fly or stand-up equally, but you can't say the same with vintage gear. I'm getting way off topic here.
Bottom line, there's only so much you can improve on a base design or concept. Anything more would be simply tweaks and adjustments.
