For the past few years since 'discovering them' these are my 'go to' spinners / lures which have been highly successful for me in catching spring and autumn salmon together with a few seatrout. I always use the silver bladed / black rubber ones in all sizes (8g, 11g, 16g and 22g), using the size appropriate to the river and prevailing conditions. Previously to using these I had limited success with Flying Cs and the standard range of Mepps. As a testament to the difference these spinners make I have been fishing on a number of occasions with a group and with other fishers that are using 'run of the mill' flying Cs and other lures, and I've managed to out catch them on nearly all occasions. The body mass and particularly the longer blade on the Rollas provides the opportunity to fish it relatively deep and slow, just like the traditional way of presenting a devon minnow. For me this provides a fatal attraction to the fish and many of my fish have been caught by this means. Having said that I have caught fish spinning with the Rollas downstream and across the current at a medium pace. The Owner hooks are excellent and don't distort under pressure (I've caught several double figure fish up to 18lbs so far!). Even managing to free them from snags I have not managed to bend the hooks out of shape as yet. I eluded in the 'Cons' to being a tad expensive - certainly in comparison to bog-standard Flying Cs. I think the Rollas could sell a little cheaper especially when two or three can easily be lost in a session! But then again they are half the price of Rapalas and I've lost quite a few of those in my fishing career. I thoroughly prescribe the use of these Rolla Silver Bullets. For my sins I have been persuaded to acquire a few Rolla Flying Devons (even more expensive!) to try in the coming months of the season - hopefully tight lines with these!
