glory, we are near the end of development of the vsm project. after sixteen years and six new versions of it i have gone through the whole thing numerous times. nothing newly developed is ever a long way down the refinement path. and because i have elected to finish my work and not proliferate designs, i think you heard the benefit to that end. plus the cost of merlin upgrades are very inexpensive for what you get in the end. imho, the master bam and master rc's are a perfect example of this.
