McHale seem very popular.McHale round bale squeezes (i think R5, extremely similar anyway). Work extremely well. We also have some of the twose spike ones with tubes, they are OK and more versatile of a tool, but for moving wrapped bales the mchale are better. They can pick up a square squeezing it end to end up to about 6ft long (just) or lengthways if its a tight enough bale. would definitely recomend. Other thing about that style is that they allow you to stack them on their ends rather than on their sides (for rounds) meaning when the birds land they dont rip the wrap so badly as there are more layers on the ends than on the sides. Its possible with the spikes, but not as easy.
