I flew with a bloke like that at one time. Did quite a lot of flying with him as it turned out. It all started from the first time I flew with him and he was doing the first sector. I was a bit alarmed by that first high speed visual approach so, when it was turn to have a go, I stuck to the SOPs and, yes, he said I was being "wussy", or some such thing.
Anyway, rather than getting upset, I asked him to teach me how to do it and get it right every time. He did. And I did. I never used that sort of approach in anything but visual approach type weather and certainly not with other skippers.
However, there was one time when, on my sector, ATC had asked me to keep the speed up during approach, for sequencing purposes. That's when I found the real value of the technique. I took the precaution of briefing the skipper on my intentions for the approach, so that he was in the loop.
He was just happy that he didn't have to take over, to ensure that we didn't lose our place in the approach queue! So I guess the short answer is to try to learn as much as you can from the bloke - never know when it'll be useful. Just be sure to brief the skipper on your intentions before you start!
