what aftermarket apex seal would you choose?

RA seals here to date. I haven't managed to bend or break any yet, but I can't say what housing wear is like until I pull down an engine that's been pushed hard.

I saw an FD engine recently that had done 5000km with Als seals and both the housings and seals still looked like new. It didn't have a heap of hp though - 330rwhp and 100:1 TTS premix. I also saw an SCR seal from an engine that had done 2000km with even less hp and what a mess - it was half worn away, more so at one end, and had a bad flat spot on the leading edge.

I'm keen to give Goopy seals a go, by all accounts they work well. It sounds like Goopy and Als are similar material.
