I’m assuming that you are talking about the John Allerton Waggler rod which has a rolled, as opposed to a sliced tip.
In that case, your choice comes down to your preferred length.
The Allerton Waggler rod is only available in 13′, and the Trilogy in 14’+
I wouldn’t recommend the Allerton Premier rod on still waters, it has been designed really for stick float fishing.
Personally for an all-round stillwater silvers rod, I’d go for the Allerton Waggler. Other than big waggler/slider fishing, I don’t think you’d need a longer rod.
The waggler rod is a beautiful piece of kit by the way.
