Spool-slip when casting with a multiplier reel is a problem that anglers and dedicated power casters have always had to contend with. Slippage is bad enough with standard sized reels like the Daiwa 7HT Mag and Abu 6500 models, but things get even worse when using larger casting multipliers.
Anglers with average sized thumbs can toil to achieve good spool purchase with the popular bigger reels such as the Daiwa Saltist 30H, Abu 7500 and Penn 535 Mag. This is chiefly because getting adequate flesh and bone clamped over the top of the spool for failsafe gripping can be something of a physical impossibility for many people.
To make matters worse, wet skin isn’t the ideal brake-pad for fastening a secure grip on greasy mono line either. Indeed the difficulty can be likened to pressing down hard on a wet bar of soap which will happily catapult right out of your restraint given the slightest opportunity.
So, the ability to grip the spool securely and comfortably is crucial, and many anglers conscious of what is a universally serious problem, resort to using something called a ‘thumby’. A thumby is simply an inch-long rubber, or rubber-like, casting grip that sleeves over the thumb. They are commonly cut from bicycle inner-tubes, or from the fingers of household rubber gloves. Their purpose is to kill slippage by adhering to the mono, locking the spool down firmly under thumb pressure for confident and safe casting.
Unfortunately, homemade thumbies tend to be of limited usefulness - not least because perhaps one in a thousand anglers will actually find one that fits absolutely perfectly. As the hands get wetter, and bait juice etc inevitably works its way under the grip, one that is too loose is inclined to fly off in the course of casting. Conversely, one that is too tight will uncomfortably constrict blood circulation and give you a big blue thumb that throbs like hell. Most anglers compromise and suffer one indignity or the other…but it doesn’t have to be like that.
Arguably better than a thumby, is a thumb-strap, sometimes cheekily referred to as a ‘strap-on’! This is basically an enveloping flap of rubber material that affixes to the reel foot, and remains in place on the reel for the duration of the fishing session. The gripping principle is the same, in that the loose strap is pressed down against the open area of the spool to massively improve purchase and grip for casting. When a cast is released, the angler lifts his thumb clear as normal and the strap automatically falls back from the spool, allowing unimpeded line flow and full inertia.
A thumb-strap is a simple and highly effective anti-slip, anti-frap device that takes all of five minutes to make… and we reckon that’s five minutes very well spent. Incidentally, the rubber shown in the sequence is used for making haemorrhoid-cushions… love your bum!
