Thanks all, been quite happy with my 510s and the couple of 901 attys I have tried (with adapters). In a PM someone mentioned 401s are good for noticing subtle flavor differences. I did a forum search for "401" and "401 atty" and got a bunch of thread results but none of the threads in the results list seemed to mention "401". So I thought to post this thread to ask so I could get something to try. First thought to get a device but why do that if I can get the adapter and atty and use what I have(?).
Thanks again!
