tonearm for soundsmith smmc 2 and dd turntable

I have a Technics sp10 mkii and a soundsmith smmc 2 cart. I also have a shure cart for use on less than mint lp's. The 3009 mkII unimproved tonearm I have is a pain to set up when switching between cartridges. Any advice on a simpler tonearm to swap out cartridges on? I have read the Epa 100 is a great tonearm, but is it easier to set up? I have a massive plinth that will not be easy to drill out for other armboards. Thanks for any help!
