RainEQ: Crashes and fixed version?

[SammysHP]

I'm looking for ways to speed up my HP 48G even more. Today I deal with RainEQ.

The problem: Several users report issues/crashes with RainEQ. At hpcalc.org the author of RainEQ explained in 2012:

Hello,
Sorry for the crashs. It's due to the return from RPN decimal->str to ASM after a possible garbage. The equivalent asm code takes quite more bits than the simple RPN call.

But there's no update, no patch, no solution, last release from 1998.

I wonder if the standalone version of EQW from MetaKernel would be an alternative. What is your experience with RainEQ and EQW? Will EQW replace the built-in equation editor automatically (when using SpeedUI)? Are there any major pros or cons (except the crashes and the bigger size of EQW)?
