I'm planning on writing up a review on a number of synthetic knots. In an effort to keep the variables to a minimum I've ordered a number of 24mm knots and plan on temporarily mounting them in the same style brush handles and at the same depth. I understand that a better comparison would be to mount these knots to the same loft but I'd prefer to avoid having to buy handles for each knot at this point and am hoping to simply swap the knots. To this end I'm curious as to which adhesive everyone would recommend for temporary mount. I know I've seen someone mention hot glue at one point and rubber cement also seems like a possible choice. Ideas, gents?
