@Silverfisher I use both flick tip is great for river small to medium fish, if think it's going to be a medium to large fish to hand day the elastic or Stillwater where the carp might get involved. If you get the right whip a system whip might come with both.
Being as old as I am and a Londoner to boot I have had years of experience using what is now termed a telescopic whip but we used to call a pole.
Before carbon we had fibreglass poles that had a maximum usable length of seven metres. In the main these poles were telescopic. We used to fish these with a short line, not to hand. The technique for shipping in was to collapse the sections into the butt section until the fish could be swung to hand or netted. Shipping out was the reverse, the sections just pulled from the butt.
This of course meant that on canal towpaths we never had to ship back across the path of walkers and cyclists.
Using this method also means that your 3m rig can be cut down so you have minimal line between tip and float.
Whip fishing in my mind is about speed fishing for small fish. The rig is always fished to hand with the rig being a little shorted than the length of the whip so when a fish is swung in it comes straight to the hand
I guess the question might be ' why a whip' ? - Dependent on your budget you can pick up a budget margin / pole that breaks down for less than £50 and some come with elastic / a spare top. - Some bargains on facebook market place too.
Think someone said making your own pole rigs is a good skill for the future and long term cheaper than buying ready made ( though they are loads better than they used to be)
I'd go 2nd hand pole - Once you start elasticating a whip its moving away from its purpose really
Keep asking questions though - No such thing as a daft one - and we all need to keep angling alive and get the kids involved.
