I think that, perhaps, this is a bit overkill for your Tamron lens. What kind of tripod head and clamp do you use on your tripod.
Often a decent quality Arca Compatible head and clamp will solve the movement problem.
Here are examples of two different Arca Compatible ball heads, The large one is a Giottos MH1300 and the smaller head is an Adorama Flashpoint F1...
I use the smaller head on a SLIK tripod modified as a travel tripod. Even though the F1 head is relatively small...
It can hold a camera and my 70-200mm f/4L IS lens quite securely.
If I were looking for a general purpose tripod head, I would use a bit larger one, like the Flashpoint F2 and I would combine this with an L bracket on my camera.

The L plates (L Brackets) by Really Right Stuff or Kirk are quite expensive but are well made.
However, eBay now has Chinese knockoffs of the RRS and Kirk plates at a much reduced price. I have one for my 7D Mark II and it seems every bit as well made as the RRS plates which can be up to 10x as expensive.

The plates are usually specific for each camera so that you can access batteries and other compartments without having to remove the plate from the camera.
The great advantage of an L Plate is that you can switch from horizontal to vertical without hanging the camera cantilevered over the side of the tripod head. The L bracket keeps the weight of the camera directly over the tripod and head whether it is in the horizontal or vertical position.
BTW: Most tripod heads are interchangeable and some non-Arca Compatible heads can be changed to Arca Compatibility simply by replacing the clamp.
Arca Swiss Release Systems are both a brand and a type of clamp. They were first made by the Arca company of Switzerland but now, just about any clamp with those characteristics will be branded as Arca Compatible. My two (actually three if you include the table top model) are equipped with Arca Compatible heads and clamps while my monopod has an Arca Compatible swivel clamp...
